本文件的范围是提供选择与电力设施系统相连的同步发电机系统中性点接地等级和方式时的基本因素和一般考虑因素。它还提供了用于实现所需接地的建议方法和设备。这些指南适用于电力设施系统中的大型和小型发电机。本指南中使用的接地术语定义见IEEE Std C62。92.1.

The scope of this document is to provide the basic factors and general considerations in selecting the class and means of neutral grounding for synchronous generator systems connected to electrical utility systems. It also provides the suggested methods and apparatus to be used to achieve the desired grounding. These guidelines apply to both large and small generators found in electrical utility systems. Definitions of grounding terms used in this the guide can be found in IEEE Std C62.92.1.
